Neighbours system how does it work?

I'm not sure how to post a photo on here but I've created a little camp site with my brown houses, they sit facing the centre which has the first Christmas tree & a little camp fire with a play area to the side & a kwickimart for holiday makers to shop in :). It takes up quite a bit of land but looks much nicer than house farms. There's 7 brown houses, the log cabin that smoke comes out of when tapped, nelsons house & cleatus farm are to the side as if they used to be part of the camp site at some point & my krustyland bus stop is just outside the site so again looks like it should be there to take holiday makers to the theme park :) I've done something similar with my skips diner size shops, they all sit around a fountain to make a little mini mall type area with the peanut cart too, again it takes up a lot of my available land so these are the only 2 big "designed" areas at the moment. I've expanded the land around Krusty burger & glup&blow to make proper drive thrus with the snow plow at the Krusty burger window so it looks like they are ordering. I 'borrowed' that idea from a showcase picture. I've just moved my prison & hospital as they were infront of Burns mansion which I didn't think he would be too happy about...can't believe I even thought that but it made me giggle.
